Having learned English, French, German, Polish, Spanish and Portoguese I am ready to share my secret to the world: read comics. They are the only written form of the colloquial language, the one you'll need mostly. Literally 100% of what you learn in a comic will be useful in your daily life. Read a novel and this drops to probably 50%, read a newspaper and it's even worse. Nobody speaks like a book or a newspaper. We speak like comics.

P.S. I learned those while living in those countries, so I was exposed to the spoken language too. Plus, comics worked for me, they won't work for everybody. At the end the real trick is to try several methods and find the one which suits you best.
